METODO E DISPOSITIVO PER LA GENERAZIONE E L'AUTENTICAZIONE DI UNA CHIAVE CRITTOGRAFICA UTILIZZATA PER LA RECIPROCA AUTENTICAZIONE DI DUE STAZIONI MOBILI

摘要

This document describes a method and device for the generation and authentication of a cryptographic key (K) used for the reciprocal authentication of two mobile terminals (1, 2) that intend to set up a communication in which the cryptographic key is extracted from information relating to at least one feature of the communication channel (h) used by mobile terminals exploiting the coherence time of the communication channel (h).
